APPARATUS FOR DISPOSING OF FOUL GASES.

SPECIFICATION forming part of Letters Patent No. 736,946, dated August 25, 1903. Ap nmtm filed January 13, 1902. semi No. 89,599. (No model.)

To all whom it .mcty concern;

Be it known that I, EUGENE R. EDSON, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Apparatus for Disposing of Foul Gases and Vapors; and I hereby declare the following to be a full,clear,

and exact description of the invention, such to as will enable others skilled in the art to which it pertains to make and use-the same.

My invention relates to improvements in apparatus for disposing of foul gases and vapors.

The object of this invention is to provide apparatus for disposing of foul or ill-smelling gases and vapors emanating or arising from material which is being dried or rendered or otherwise reduced and to avoid expelling or discharging the said vapors and gases into,

and thereby contaminating, the external atmosphere and to partially utilize the said gases to advantage.

With this object in view and to the end of z 5 realizing other advantages hereinafter appearing-such, for instance, as providing an apparatus of the character indicated which is simple and durable in construction and re- .liable in its operation-my inventionconsists go in certain features of construction and combinations of parts hereinafter described, and

pointed out'in the claim.

In the accompanying drawings, Figure I is a side elevation, partly in section, of apparatus embodyingmy invention and illustrates a partial utilization of the foul or ill-smelling gases and air in facilitating the combustion within a furnace wherein the said gases are consumed. Fig. 11 is a side elevation, largely to in central longitudinal section, of the tank wherein the insoluble gases are separated from the gases or vapors which are soluble in water.

Referring to the drawings, a designates a s tank, which is preferably in the form of a cylinder arranged in a horizontal plane. The chamber of the tank a is supplied with water preparatory to the operation of the apparatus, and a depth of water, having the water- 0 level within the upper portion of the said tank, is maintained during the operation of the apparatus. The water-inlet of the tank a is preferably arranged at the bottom and centrally between theends of the tank. Preferably a pipe-fitting b is attached to the bottom of the tank a centrally between the ends of the tank and in open relationwith the water-receiving chamber in the tank. A valved Watersupply pipe 0 connects and is in open relation with the pipe-fitting b and has its valve d normally closed. A valved drainpipe e, having its valve f normally closed, extends from the pipe-fitting b to a waste-pipe g and is attached to the said wastepipe and to the said pipe-fitting. The pipe 6 is instrumental in establishing open relation between the chamber of the tank a and the waste-pipe g. The waste-pipe 9 extends above and below the drain-pipe 6, extending downwardly below the said drain-pipe to and communicatingwith a pipe h, adapted to feed a sewer,

and extending upwardly above the said drainpipe to the top of the tank a, where it, the said waste-pipe g, communicates with the chamber of the said tank at one end of the tank and at the elevation of the level of water which is to be maintained within the tank during the operation of the apparatus.

By the construction hereinbefore described the tank at is supplied with water or drained, according as the valve cl of the pipe 0, or the valvefof the pipe e, is opened; but of course the valvef is only opened when the tank a needs'cleaning internally, and sediment aecumulating upon the bottom'of the chamber of the tank is removed into the waste-pipe g through the pipes upon opening the valve f. The foul or ill-smelling vapors and gases which are to be disposed of and to the best advantage are conducted into the body of water within the tank a during the operation of the apparatus, and such of the said gases and vapors as are soluble in the water are absorbed into and difiused throughout the body of water and conducted 0% with the water flowing into the waste-pipe g. The valve d of the water-supply pipe 0 is ofcourse opened and left open during the operation of the apparatus, and the supply of water to the tank a is so regulated by the valve 61 that a continuous flow of liquid from the said tank into the waste-pipe g obtains (l uring the operation of the apparatus. Any gases or air conducted into the tank and not soluble in or convey able off with the water flowing from the tank into the Waste-pipe are disposed of, preferably, by conducting them to the ash-pit of a stove or furnace and there causing them to pass through the grate into a fire upon the grate, Where they are consumed and facilitate the combustion.

Fig. I of the drawings shows a furnace i, andj designates the combustion-chamber of the furnace, is the grate, and Z the ash-pit below the grate. A pipe m has its discharging end arranged within the ash-pit in suitable proximity to the under side of the grate and extends from the furnace to the top of the tank a, where it is in open relation with the chamber of the said tank. Preferably the waste-pipe g communicates with the chamber of the tank aat an elevation somewhat below the inlet of the pipe m, so that there is no liability of water entering the pipe m, which extends, preferably, somewhat above the tank. Any gases and vapors or air received within the tank a and not carried 06 in solution with the water flowing from the said tank are conducted from the tank by the pipe m to the furnace for consumption.

The means employed for introducing the gases and vapors which are to be disposed of into the chamber of the tank 0. comprises, preferably, a perforated pipe-section n, arranged horizontally within the lower portion of and in close proximity to the bottom of the said chamber. The pipe-section n is supported in any approved manner and extends, preferably, through one end wall of the tank a to near the inner surface of the other end wall of the tank, being closed at its inner end, 7

as at 0, and attached at the said end, as at 10, to the adjacent end wall of the tank by a bolt and a nut or other fastening device, so as to steady the said pipe-section during the operation of the apparatus. The pipe-section n has its lower portion provided with a plurality of series of orifices 1', with each series arranged longitudinally of the pipe-section and a suitable distance apart laterally and with the orifices of each series arranged at short intervals longitudinally of the pipe-section. The pipe-section n is connected and in open relation at its outer or receiving end with the discharging end of a valved pipes, which connects and is in open relation with the outlet of a suitably-operated pump it, which is arranged at an elevation below the tank a. The pipe 8, outside of and. next adjacent to the tank a, has a convolution 14 arranged in a vertical plane and extending preferably above the tank a, or at least above the waterlevel maintained within the tank during the operation of the apparatus, so that water cannot be conducted from the tank through the said pipe 8. The inlet of the pump 25 is connected and in open relation with the valved pipe I), which extends from and is in open relation with the chamber of a drier or rendering or reducing apparatus or any vessel or receptacle x,containing or supplied with gases and vapors which are to be disposed of without contamination of the external atmosphere. The valves q of the pipes 12 and s are of course opened, if not already open, preparatory to the operation of the pump 15.

It will be observed that the location of the perforated pipe-section n in close proximity to the bottom of the chamber of the tank a is important, because thereby the gases and vapors are introduced into the body of water within the said chamber farthest below the outlets of the chamber, and any soluble gaseous or aeriform body passing into the said body of water will likely have been absorbed or diffused in the water before it reaches the said outlets, so that only gases and air not soluble in water will pass from the tank into the pipe which conducts the said last-mentioned gases and air to the furnace. It will be observed also that the pumping of the gases and vapors and accompanying air into the tank a and any suction created by a draft through the furnace materially expedite or facilitate the passage of gases to the furnace. I would also remark that a trap g is provided at the junction of the waste-pipe g with the said sewer-feeding pipe h, so as to form a liquid seal which will effectually prevent the passage into the sewer h of any gases which escape into the said pipe 9 without entering into solution with the said water passing into the said pipe g, and hence it will be observed that gases and vapors not entering into solution with the water in the tank a cannot escape passage to the furnace.

What I claim is Apparatus of the character indicated, comprising a tank having an outlet at the top for any gaseous or aeriform fluid not soluble in water, a valved water-supply pipe communicating with the chamber of the tank at the bottom of the tank, a perforated pipe-section arranged within and near the bottom of the said chamber and extending longitudinally of the tank, a pipe for conducting gases and vapors to the tank andin open relation with the said perforated pipe-section, a sewer-feeding pipe arranged a suitable distance below the tank, an upright pipe or passage-way in open relation at one end with the said sewerfeeding pipe and communicating at its opposite end with the upper portion of the aforesaid chamber, and a valved drain-pipe communicating with the aforesaid chamber at the bottom of the tank and discharging into the aforesaid upright pipe.

In testimony whereof I sign the foregoing specification, in the presence of two witnesses, this 8th day of January, 1902, at Cleveland, Ohio.

EUGENE R. EDSON.
